TWIB blogged about a little something we have been working on with the Bazaar guys. The Bazaar mirror now has loggerhead and search, based on the bzr-search plugin. This lets it search over the whole history of trunk. When beuno finishes skinning it i’ll integrate it in to the main site. In the mean time, enjoy.
Oh, it also shows off something I badly explained the other day. See here. Revision 5 was committed by myself, but bzr-svn also saved the –author property, attributing that code to Jelmer correctly.
Just notice, that there are efforts to improve hg svn which is currently a GSoC project.
